Abstract:The macular carotenoids (i.e., lutein (L), zeaxanthin (Z) andmeso-zeaxanthin (MZ)) exhibitanti-inflammatory, antioxidant and optical properties that are believed to support human healthand function. Studying the accumulation and distribution of these nutrients in tissues and organs,in addition to the eye, is an important step in understanding how these nutrients might support globalhuman function and health (e.g., heart and brain). Chicken is an appropriate animal model withwhich to study the accumulation of these carotenoids in organs, as the relevant transport moleculesand carotenoid binding proteins for L, Z and MZ are present in both humans and chickens. In thisexperiment, a sample of 3 chickens that were supplemented with L and MZ diacetate (active group)and a sample of 3 chickens that received a standard diet (control group) were analysed. Both groupswere analysed for L, Z and MZ concentrations in the brain, eyes, heart, lung, duodenum/pancreas,jejunum/ileum, kidney and breast tissue. L, Z and MZ were identified in all the organs/tissuesanalysed from the active group. L and Z were identified in all of the organs/tissues analysed fromthe control group; while, MZ was identified in the eyes of these animals only. The discovery that MZis accumulated in the tissues and organs of chickens supplemented with this carotenoid is important,given that it is known that a combination of L, Z and MZ exhibits superior antioxidant capacity whencompared to any of these carotenoids in isolation.
